AIRAID Air Intake Systems

PowerAid™ Throttle Body Spacer (400-633) by AIRAID®. Color: Red. Finish: Anodized. Material Used: Aluminum. Thickness: 1" (25 mm). Quantity: Sold individually. Includes: Gaskets, Mounting Hardware. The patented Helix Bore in the PowerAid™ Throttle Body Spacer causes a spinning action of the incoming air charge as it passes through the throttle body. This turbulent airflow greatly improves fuel atomization, resulting in more complete combustion and greater engine efficiency. This produces tremendous gains in low end torque and better fuel economy. The PowerAid™ spacer is easy to install, it's 50 state legal, will not void new car warranties, and can be used with any grade fuel.

There are many companies that make products to improve airflow to your engine. AIRAID is one of the few that's thought of how to improve that airflow once it gets there. The result of their research and testing is the PowerAid™ Throttle Body Spacer. The PowerAid™ Spacer is about 1-in. thick and installs between the throttle body and intake manifold. It features AIRAID's unique and patented Helix Bore, which creates a spinning action as the incoming air passes through the throttle body. The helical effect causes the air molecules to organize and maintain high velocity, all the way into the combustion chamber. Combustion is improved and engine efficiency increased. The results you experience are tremendous torque gains from 800-2500 rpm, along with gains in fuel economy.

Each PowerAid™ spacer is computer designed and dyno tested for the specific application. It's manufactured from high quality, aircraft-grade 6061 T-6 aluminum. Everything required for installation comes with your spacer, including gaskets, hardware, the necessary brackets and detailed instructions. And it can be installed in less than an hour with simple hand tools.

PowerAid™ spacers are available for vehicles with electronic throttle bodies and vehicles with throttle cables. They're also available with PowerPorts™. PowerPorts™ are specially located ports in the spacer that are drilled and tapped for instrumentation sensors or power enhancements like Nitrous Oxide.

PowerAid™ spacers are 50 state legal, will not void new car warranties, and can be used with any grade fuel. And they're backed by AIRAID's "No Hassle" warranty. There are no limitations or fine print here. Simply, if you're ever dissatisfied with the materials, workmanship, or performance of this PowerAid™ spacer, just send it back... period! You don't have to worry about a proof of purchase or a warranty card. AIRAID air intake systems are warranted for life.

AIRAID® was founded in 1997 when they began developing and manufacturing air intake systems for light trucks and SUVs, utilizing the cotton-gauze filter technology that was available at the time. These systems increased airflow and performance while being easy to install, and sold so well that the company soon realized that another source of filters was necessary. They believed they could produce a better quality filter using new technology and state-of-the-art materials, and so in 2002 the AIRAID Filter Company was formed. Today AIRAID is the recognized leader in air management technology. Extensive research and development has allowed AIRAID to come to market first with high quality products that improve drivability and performance.
